#1. "RE: Can FV lock only be setup as a custom function button on D7000?" In response to Reply # 0
You can use Custom Setting f2 to assign the Function button for FV lock or f4 to assign the AE-L/AF-L button for FV lock. If you use the MB-D15 you can also use f9 to set the AE-L/AF-L button on the MB-D15 for FV lock.
